The symbol ⟨ɣ⟩ is also sometimes used to represent the velar approximant, though that is more accurately written with the lowering diacritic: [ɣ̞] or [ɣ˕]. The IPA also provides a dedicated symbol for a velar approximant, [ɰ], though there can be stylistic reasons to not use it in phonetic transcription.

There is also a voiced post-velar fricative (also called pre-uvular) in some languages. For voiced pre-velar fricative (also called post-palatal), see voiced palatal fricative.

^Phonetic studies such as Quilis (1981) have found that Spanish voiced stops may surface as spirants with various degrees of constriction. These allophones are not limited to regular fricative articulations, but range from articulations that involve a near complete oral closure to articulations involving a degree of aperture quite close to vocalization
